The 27.3 kilometre Semmering Base Tunnel will connect Gloggnitz in Lower Austria with Mürzzuschlag in Styria from 2030. The journey from Vienna to Graz by train will take less than two hours when one of the longest railway tunnels is completed. voestalpine Tubulars is ensuring safe tunnelling with high-strength steel grades of mechanical tubes and is meeting the complex requirements of the project.
The multi-layered rock structure with hard, soft, dry and water-bearing layers requires special measures such as injection drilling, for which the high-quality mechanical tubes from voestalpine Tubulars are ideally suited.
Via the indirect sales channel and in close co-operation with long-standing partners, our pipes are delivered just-in-time and ready for installation directly to the construction site. Our pipes are then used in a special injection drilling process and successfully withstand the geological and geotechnical challenges.
